Math Adventures: One More & One Less – Learning about numbers – ‘One More’ concept – If we have 3 apples, one more would be 4 apples. – ‘One Less’ concept – If we have 5 ducks, one less would be 4 ducks. – Counting with pictures | This slide introduces the concepts of ‘One More’ and ‘One Less’ to Kindergarten students, using visual aids to enhance understanding. Start by engaging the students with the idea that numbers are fun and part of everyday life. Explain ‘One More’ by adding a single item to a group and counting the new total. Similarly, demonstrate ‘One Less’ by removing an item and counting what remains. Use pictures to illustrate these concepts, as visual learning is very effective at this age. Encourage the children to participate by asking them to visualize adding or taking away items from familiar objects like toys or fruits. This interactive approach will help them grasp the concept of incrementing and decrementing numbers by one.

Understanding ‘One More’ – ‘One More’ adds 1 to a number – Example with 3 apples – If we start with 3 apples and add one more, we have 4 apples. – Counting one more together – We’ll use images to count 1, 2, 3, and then add one more for 4. – Using pictures to learn – Visual aids help us see the concept of adding one more. | This slide introduces the concept of ‘One More’ to Kindergarten students by using a relatable example of apples. Start by explaining that ‘One More’ means we are adding one additional item to what we already have. Use pictures of apples to visually demonstrate this concept. Show three apples, then add one more and count all the apples again, emphasizing the new total of four. This visual and interactive approach helps young learners grasp the idea of incrementing a number by one. Encourage the students to participate in counting and to think of other examples where they might add ‘one more’ of something in their daily lives.

Let’s Practice ‘One More’! – Observe the picture carefully – Find ‘one more’ than the number shown – Example: Ducks in a pond – If there are 4 ducks and one more joins, how many? – Count the total number of ducks – After one more duck joins, we count all the ducks again | This slide is designed to help Kindergarten students practice the concept of ‘one more’ using visual aids. Start by showing a picture with a certain number of objects, such as ducks in a pond. Ask the students to count the objects. Then, introduce ‘one more’ by adding another object to the picture. Use the example provided to guide the students through the process: if there are 4 ducks and one more joins, ask the students to count again to find out how many ducks there are now. Encourage the students to use their fingers to count and ensure they understand that ‘one more’ means adding one to the original number. Repeat this activity with different pictures and numbers up to 10 to reinforce the concept.

Understanding ‘One Less’ – ‘One Less’ means taking 1 away – Example: 5 balloons, 1 pops – If we start with 5 and take away 1, we have 4 balloons left – Count remaining balloons – Let’s count: 1, 2, 3, 4. That’s one less! – Visual learning with pictures – We’ll use images to help us see the change | This slide introduces the concept of ‘One Less’ to Kindergarten students using a relatable example of balloons. Start by explaining that ‘One Less’ means we take away one from any number. Use a picture of 5 balloons and visually demonstrate one balloon popping. Then, count the remaining balloons with the class to reinforce the concept. Visual aids are crucial for this age group, as they help children understand abstract concepts like subtraction in a concrete way. Encourage the students to visualize the concept by drawing or using objects they can touch. This interactive approach will help solidify their understanding of ‘One Less’.

Let’s Practice ‘One Less’! – Understand ‘one less’ concept – Observe picture scenarios – Example: 6 cookies, eat 1 – Start with 6, eat 1, how many left? – Discuss ‘one less’ results – If we have one less than 6, we have 5 cookies left. | This slide is aimed at helping Kindergarten students grasp the concept of ‘one less’ through visual aids and interactive examples. Start by explaining that ‘one less’ means taking away one item from a group. Show them pictures depicting various scenarios, such as cookies on a plate, and ask them to visualize someone eating one. Use the example of 6 cookies, and if someone eats one, ask the students how many are left to help them understand the concept of subtraction as ‘one less’. Encourage the students to use their fingers or counters to physically remove one and count the remaining items. This hands-on activity will help solidify their understanding of the concept.

Counting Stars: One More and One Less – Understanding ‘One More’ and ‘One Less’ – See ‘One More’ and ‘One Less’ together – 7 stars: one appears, one falls – If we start with 7, add 1, lose 1, we still have 7 – Visualizing with star pictures – Pictures help us see the changes – Balancing ‘more’ and ‘less’ | This slide is designed to help Kindergarten students visualize the concepts of ‘One More’ and ‘One Less’ using a scenario involving stars. Start by explaining that when we have a certain number of items and we add one more, the total increases by one. Conversely, when one item is taken away, the total decreases by one. Use pictures of stars to illustrate this concept, showing 7 stars, then adding one to the group, and then taking one away. This will help students understand that the number remains the same if one is added and one is subtracted. Encourage the students to use their fingers or counters to add and subtract one from different numbers up to 10. This hands-on activity will reinforce their understanding of the concept.

Class Activity: One More, One Less Game – Play ‘One More, One Less’ with objects – Take turns adding or removing an object – Count together after each change – Understand ‘one more’ and ‘one less’ – Example: If we have 4 apples and add 1, we have 5 apples. If we take 1 away, we have 3. | This interactive activity is designed to help Kindergarten students grasp the concept of ‘one more’ and ‘one less’ in a tangible and engaging way. Provide a variety of objects for the children to use, such as blocks, toy cars, or fruit. As each child takes a turn, they will either add one object to the group or take one away. After each action, the class will count the objects together to reinforce the concept of addition and subtraction by one. Encourage the students to observe the changes in quantity and use the terms ‘one more’ and ‘one less’ to describe them. Possible variations of the activity could include using a number line, having students draw the changes, or using a song to accompany the counting.
